I was amazed to find that I didn't need to tip the piano. It will still 
wick in. You just
don't use too much, and have a towel underneath to catch any that runs off.

If it doesn't beef up the holding ability, try a second dose of it.
I figure that the first dose wicks into the tiny cracks and goes miles
in a few seconds. This starves the area right around the tuning pin. But
the second dose can't run for miles in a few seconds, because the cracks
have been sealed by the first dose, so it stays closer to the pin and helps
it hold.

Well, that's a theory, but a comforting one. And the second dose often does
seem to work better than the first.
